Its got 4 flanges that act like teeth, attached to a long pole of piping, with a T handle. It turns clockwise, I saw my first one last week end, the operator was cleaning out post holes made by a hand auger. The device appeared to be maybe 40 or more years old, and I have never seen one for sale anywhere. The cutting/digging head is circular, at about the same size as a regular pair of manual post hole diggers. Is there a more correct name, so I can try to find one? Looks like it was doing a very good job on this Florida sandy soil. About 3 half turns did fill it up. Edited to add; I just looked at about 20 pages from Goggle and do not see anything similar, I should mention that the item's flanges are internally spherical orientated, enough to form a 'basket' for the removed earth. Yes, I saw the currant hand augers, but they feature a round disc that has a cutting head, apparently for cutting into clay or similar before removing via standard post hole diggers. The device I am talking about gathers its basket full of sand, then must be removed to be emptied before continuing to dig. One half of the bottom of the basket is open space, the other half is the flanges. It looks like something that worked extremely well but fell to the way side as power equipment came along.
